Medina was optioned to High-A Hudson Valley on Friday.
The organization has expressed high optimism for Medina, but he's only 21 years of age and needs more seasoning, so he'll open the campaign in High-A ball. The right-hander has made one Grapefruit League appearance this spring, allowing one run on four walks over two-thirds of an inning. Control has been Medina's primary struggle in his short professional career, so he'll need to work that issue out before he's ready to tackle the majors.
